2-Iodothiophene (TP-I, Thiopheyl iodide, 2-ThioPhenyl iodide) is used as an intermediate in the synthesis of TP2P (ThioPhenyl-2-Propanone, 2-Thienylacetone). 2-Iodothiophene can react with ethyl acetoacetate and sodium ethoxide using CuI (Copper Iodide) and then reacted with hydrochloric acid and heated. 2-Iodothiophene can also undergo grignard reactions to obtain TP2Pol (ThioPhenyl-2-Propanonl, 2-Thienylisopropanol).
2-Iodothiophene has been obtained by addition of half of 50% aqueous nitric acid dropwise to a mixture of iodine and thiophene with vigorous stirring. As soon as the evolution of gases subsided the rest of the aqueous nitric acid was added to the reaction mixture and refluxed for 30 min. The organic layer was separated and steam distilled to obtain 2-iodothiophene.
Iodination of thiophene with iodine and mercuric oxide at 0°C gave a mixture of 2-iodothiophene (70%) and 2,5-diiodothiophene. 2-Iodothiophene has been exclusively obtained by nitrating thiophene with a mixture of iodine and nitric acid at 90°C. An easy approach for iodination of thiophene is the reaction of iodine with lithiated thiophene.

Tony: I iodinated thiophene using nitric acid and slowly added it, then refluxed it for 30 minutes at 90 °C. I obtained 2-Iodothiophene.

Get the 2 Dollarsmug. A repeating .22.... or 2:9 is a trend of secondhand sensation. It the formation of or equivalency of nonsense or the partiality of control, it is a divisional line error in human trend. It is often mistook for fortune, in reality it is a way to nurture something to health or bring something to a stop, in a total halt of motion. As a fraction it works like any number mechanism, it uses motion force, like a fixed motor, it does not respond to human interaction or process interaction.
(2÷9) or .2222...22... is used as a metaphysical in any design that uses any strategy. Like that in Asimov's science fiction adaptation of Greek and Latin laws. The principle counts much like the mechanism of one table; the sensation is factored into a daily living habit: a law that drives the cost retention of most products down, just like a personal cost expense. Financially it is redundant to state, yet the ethics and mannerisms of using a mechanism like .2222.. is like the procedure of removing or the damage of a kidney. (The process will round to about three)
